Nursing Elites

1. A client with asthma develops respiratory acidosis. Based on this diagnosis, what should the nurse expect the client's serum potassium level to be?

• A. normal
• B. elevated
• C. low
• D. unrelated to the pH

Correct answer: B

Rationale: In respiratory acidosis, the body retains CO2, leading to increased hydrogen ion concentration and a drop in blood pH. As pH decreases, serum potassium levels increase due to the movement of potassium out of cells to compensate for the acidosis. Elevated serum potassium levels are expected in respiratory acidosis. Choice A ('normal') is incorrect because potassium levels are expected to be elevated in respiratory acidosis. Choice C ('low') is incorrect as potassium levels rise in this condition. Choice D ('unrelated to the pH') is incorrect as serum potassium levels are directly impacted by changes in pH in respiratory acidosis.

2. What is one characteristic of human immunodeficiency virus (HIV)?

• A. The presence of circulating antibodies that neutralize HIV is evidence of exposure to HIV.
• B. HIV replication occurs intracellularly.
• C. HIV integrates its genetic material into the host cell's DNA.
• D. DNA replication is irrelevant to HIV.

Correct answer: C

Rationale: The correct answer is C. HIV integrates its genetic material into the host cell's DNA. The virus uses the enzyme reverse transcriptase to make a DNA copy of its RNA, which is then inserted into the genetic material of the infected cell. Choice A is incorrect because the presence of antibodies does not indicate immunity to HIV but rather exposure to the virus. Choice B is incorrect as HIV replication occurs intracellularly, inside the host cell. Choice D is irrelevant to the characteristics of HIV.

3. Teaching the client with gonorrhea how to prevent reinfection and further spread is an example of

• A. primary prevention
• B. secondary prevention
• C. tertiary prevention
• D. primary health care prevention

Correct answer: B

Rationale: The correct answer is B: secondary prevention. This type of prevention focuses on reducing the impact of a disease by early detection and treatment. In the case of gonorrhea, teaching the client how to prevent reinfection and further spread falls under secondary prevention because it aims to reduce the prevalence and morbidity of the disease. Choice A (primary prevention) involves measures to prevent the disease from occurring in the first place, such as vaccination. Choice C (tertiary prevention) focuses on managing the long-term consequences of a disease to prevent complications. Choice D (primary health care prevention) is not a recognized term in prevention strategies.

4. A 22-year-old patient in a mental health lock-down unit under suicide watch appears happy about being discharged. Which of the following is probably happening?

• A. The patient is excited about being around family again.
• B. The patient's suicide plan has probably progressed.
• C. The patient's plans for the future have been clarified.
• D. The patient's mood is improving.

Correct answer: B

Rationale: In this scenario, it is concerning that a patient under suicide watch is happy about being discharged as it may indicate that the patient's suicide plan has advanced. This change in behavior should be taken seriously as it can signal an increased risk of self-harm. Choices A, C, and D are less likely as the patient's happiness about discharge in this context is more indicative of a worsening situation rather than positive outcomes like being around family, clarifying future plans, or improving mood.

5. A client has a 10% dextrose in water IV solution running. He is scheduled to receive his antiepileptic drug, phenytoin (Dilantin), at this time. The nurse knows that the phenytoin:

• A. is given after the D10W is finished.
• B. should be given at the time it is due in the medication port closest to the client.
• C. can be piggybacked into the D10W solution now.
• D. is incompatible with dextrose solutions.

Correct answer: D

Rationale: Phenytoin is incompatible with dextrose solutions as they will precipitate when mixed together. Therefore, it should not be piggybacked into the D10W solution or given through the same port. Instead, normal saline should be used to flush before and after administering phenytoin to prevent any interaction with the dextrose solution. Delaying the administration of an antiepileptic drug like phenytoin to maintain therapeutic blood levels is not recommended, so it should not be given after the D10W is finished or based on the medication port closest to the client. Choice A is incorrect because administering phenytoin after the D10W is finished is not the correct approach due to the incompatibility with dextrose solutions. Choice B is incorrect as the timing of phenytoin administration should not be based on the medication port closest to the client but on compatibility considerations. Choice C is incorrect as piggybacking phenytoin into the D10W solution is not advisable due to the incompatibility issue.
